A没有用被动 found前应有be动词表被动， D是因为省略了 which were； 而且就算要用and并列，也不用加“，”

把found和dated看作做后置定语，不对么？

AlienX

A的"made it the earliest known mammal..."不對
1. it沒有指代對象
2. made的主語是Fossils of the arm of a sloth, 邏輯不對....導致the sloth the earliest known mammal on...是那個確認 - "Fossils of the arm of a sloth have been dated at 34 million years old"

ezailshi

句子结构：Fossils of the arm of sloth, ..., have been dated at..., making...
making引导的伴随状语的逻辑主语就应该是Fossils of the arm of sloth，没错啊。

was主谓不一致，making sth 错

还是不明白a为什么不对啊。。。

have been dated有什么明显的状语标志或者逻辑含义此处要用完成式吗？ 怎么读也读不通用完成时的用意，请大牛们赐教
